Is there some method to reduce the noise ?

Hi guys:

    I recorded some voice and put them into a wave file, but seems there are some noise in that ( sound like "zizizi" ). I wonder if there are some method to reduce noise. ( Seems I can not improve my MIC quality...:-) ) And I want to know more about the noise reduceing.

    Thanks, good guys.

Audacity has a noise-reduction filter you could use that comes packaged with DSP array in it. Most noise-reduction filters are usually based upon an FFT that perform's the processing and analyzing portion.  It should be pretty straightforward and simple.
